P wave: PR interval: QRS complex: (ST segment) T wave: QT interval: correct answers • P wave - atrial depolarization and contraction • PR interval - time of travel from the SA node to AV node (.12-.2) • QRS - ventricular depolarization and contraction (.08-.12) - Note: Atrial repolarization occurs during this time, but cannot be seen on EKG • T wave - ventricular repolarization • QT interval - start of ventricular contraction to end of relaxation Systematic Approach to ana...
